fixed : repair corrupt RAR-files on your Mac

Question :

I have some RAR-archive-files on my Mac that I would like to decompress/unarchive. I have tried several unarchiver-applications, but they all end up telling me that the RAR-file is corrupted.

Is there any way to fix this ?

 

Answer :

RAR (which stands for Roshal ARchive) is a very popular file-compression that is developed and maintained by the Roshal brothers Eugene & Alexander. Their RAR & unRAR utility is called WinRAR (for Windows) or simply RAR (for all other platforms including MacOSX).

One interesting thing about WinRAR/RAR is that it is also capable of repairing corrupted RAR-archive-files. Slight down-side is that the utility doesn’t have a graphic interface (GUI) like most MacOSX-apps… it is a ‘command line only’ tool…

To repair damaged RAR-archive-files on MacOSX, do this :

– download WinRAR/RAR for MacOSX from the Roshal brothers’ website :

http://www.win-rar.com/fileadmin/winrar-versions/rarosx-4.2.0.tar.gz

NOTE : if you want to be sure you get the latest version of RAR for MacOSX, go to the website to find it :

http://www.win-rar.com/download.html

– After downloading, open the Terminal app that is in the Utilities folder inside your Applications folder and drop the “rar” program file from the “rarosx” folder onto the terminal window.

– Then make sure there’s a space (by typing on the SPACE-bar of your keyboard)

– Then type “r” (without the quotes).

– Then make sure there’s another space (by typing on the SPACE-bar of your keyboard again).

– Then drop the file you want repaired onto the terminal window (it’ll give the path and name of the file).

– Then make sure there’s another space (typ the SPACE-bar)

– and type “Users/yourname/Desktop” or wherever you want the fixed file to be delivered.

(if you want to deliver to a specific destination folder, it may be easier to just drop the folder where you want it placed onto the terminal window again so there’s no chance at typos)

– Then hit “return” and the repair scan will start. if the file has a recovery record, it will say that it was found almost immediately. Then the repairing the file will start. (this might take a couple of minutes, depending on the size of the file)

– After that, double click the repaired RAR-archive-file to have it unRARed

…that should do the trick!

NOTE : the file will have the prefix “rebuilt” appended to the beginning of the filename. You’ll need to delete that once the repair process has completed before you attempt to join the files again.

    • @karan :

      Thanks for your feedback.
      The problem you are encountering isn’t clear, you’re description is a little short on useable info.

      Can you please specify what application is telling you “permission denied” and at what stadium of the process outlined in the original post you are getting the “permission denied” error ?

      Thanks !

      • i have the same error after doing all your steps and i am logged in into macbook pro as admin can you please help?

      • @filipe :

        Thanks for your feedback.
        Sorry to hear this doesn’t work for you yet.

        it isn’t clear what you mean by “the same error”, so it’s not clear what the exact problem you want help on… however :

        Going to the Win-rar.com website learns there are now 2 versions of WinRAR :
        a FREE and a payed version. The FREE version is available here :
        http://www.win-rar.com/postdownload.html?&L=0&f=rarosx-5.3.0.tar.gz&spV=true
        ( the latest version for OSX at time of writing is 5.3.0 )

        I would assume that this version of WinRAR still works as previous versions did, but please note that the original post dates from November 2012, which is over 3 years ago, so things might have changed since…

        The added value of the payed version isn’t clear to me. It turns out that the payed version of WinRAR is linked to WinZIP, a product of the Corel software company, so you might be able to get valuable info from them :
        http://www.winzip.com/land_support.html

        Good Luck !

  1. Thank you for posting such clear step-by-step instructions on how to repair corrupted .rar files.
    However, I’ve got a slightly different problem: Is there a way I can create missing (password-protected) .rar files with available .rev files through Terminal? BTW, I obviously got the password.

    Apparently it can be done easily on Windows machines and some Mac users claim they did it with UnRarX, but I just couldn’t make it work. UnRarX does recognise the recovery volumes but doesn’t do anything about it.

    Thank you in advance for your help.

    • @Nathan :

      Thanks for your compliments !

      To be honest, I don’t know of a quick solution to the problem you’re encountering.
      Sorry…
      Good Luck !

  2. sorry my English s***s
    I have problem understanding the steps you so kindly provided
    would you please post some pictures?

    sincerely,
    Jason

  3. It’s too complicated for a dolt like me. I am unclear by what you mean by ‘rar file.’ I wish someone would say, “the downloaded rar file in your downloads.” I also keyed in rarosx – that folder doesn’t exist. Thanks for your help, though! I’m sorry I am too thick to get it!! ;`[

    • @Johannes Bols:

      Thanks for the feedback.

      rar file = a file with “.rar” as it’s file extension = a file with a “.rar” file name ending = a file that has been compressed using the RAR method of file compression, and should be decompressed before revealing the original file (which could be a .jpg-picture or a .doc-Word-document or any other file type)

      “in your downloads” = located in your downloads folder (by default, your downloads folder is the folder named Downloads, but some people have chosen to redirect their downloads to some other folder ; if your downloads are not in your folder named Downloads, have a look on your Desktop, as the Desktop folder is another location that is commonly used to download files to ; else, have a look in your Safari Settings to see which folder you have set to download to)

      BEWARE : this solution involves using the Terminal-app, which doesn’t have a Graphical User Interface (GUI), so it’s only lines of computer programming code that you have to work in ; that is something only advanced computer users should do, as you risk messing up your entire Mac if you do not understand the directions given and/or you do not follow them to the letter…

      I would suggest asking someone with advanced computer skills to do this for you if you consider your own skills too basic, else you would normally be best off not trying this at all…
      If you are not an advanced user yet, you should only try this if you are interested in learning more about what’s behind the day-to-day facade of your Mac AND you have a lot of time and frustration to spare…

      Hope this helps 😉

  4. wait…i didnt understand the last part …can u explain it in easy words?the NOTE part? the file will have the prefix “rebuilt” appended to the beginning of the filename….what does that mean?

    • @Johnny Storm :

      it only means that if the original file name was “something-pt1.rar” the rebuild version will automatically be called “rebuilt-something-pt1.rar” and you’ll have to rename that to “something-pt1.rar” before you can rejoin it with “something-pt2.rar” and “something-pt3.rar” during the unRAR-ing

      does that make sense ?
      enjoy !

  5. This fix unfortunately did not work for me, however I found another method which achieved my desired result :).

    Using Wineskin Winery, I created a skin and installed the trial of winRAR (windows 32 bit)

    I opened the RAR file with the new wineskin application and right-clicked the shown folder and selected “extract to a specified folder” (Z:/Users/Name/Desktop)

    I hope this helped people having similar issues :).

    • @li0n7900 :

      Thanks for your feedback !

      And thank you for the tip on using WinRAR !

      Just one question : if you wanted to (or had to) use WinRAR, why didn’t you just use the macOS-version of WinRAR ?
      the FREE version of WinRAR 5.50 for OSX/macOS can be downloaded at :
      https://www.techspot.com/downloads/5169-winrar-for-mac.html

      I am planning to include your alternative solution in the original post, but before I do so, could you do something for me please ?
      Would you be able to test if the WinRAR for macOS would also have been able to repair your corrupt .rar-file ?
      (I hope you still have a copy of the corrupt version)

      Looking forward to hearing from you.
      Thanks !

      • I downloaded a newer version of where I got the corrupt file from, (still corrupt, I checked) and winRAR macosx

        Unfortunately I’m not very tech savvy, so if there’s a way to open the file with the mac version, I couldn’t find it

        After that attempt I tried to open the file again in the windows version of winRAR and again it worked.

        I’m sorry that I couldn’t be more help 😦

      • @li0n7900 :

        Thank you very much for the feedback.
        As I am not completely sure on the reason why you are experiencing problems,
        I have contracted WinRAR-developer RARlab on this.
        I’ll keep you posted on this when I get feedback from them.
        😉
